Miniature rose plant named Savaschool

ABSTRACT

A new miniature rose with yellow flowers of good form.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the miniature rose class, which was created by me by crossing as seed parent the variety known as `Klima` and as pollen parent the variety known as `Sonnenkind`. The varietal denomination of this new rose is `Savaschool`.

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware is its attractive yellow flowers of good form.

Asexual reproduction by propagation of cuttings of the new variety as performed in Essex County, Mass. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the flowers of the new variety in different stages of development depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Phenotypic expression may vary with light availability, environmental and cultural conditions.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart.

Parentage:

Seed parent.--`Klima`.

Pollen parent.--`Sonnenkind`.

Class: Miniature.

The following observations were made of specimens grown under glass in Essex County, Mass., during the month of September.

A. Bud:

(1) Size.--Medium.

(2) Form.--Ovate.

(3) Color.--As sepals divide, bud color is near 11B to 13D.

(4) Sepals.--Slightly longer than bud, sparsely foliated.

(5) Peduncle.--Length -- about 11/8 inches. Aspect -- straight. Strength -- erect. Color -- near 144B.

B. Bloom:

(3) Color.--New foliage: Upper side -- near 143A. Underside -- near 143B. Old foliage: Upper side -- near 137A. Underside -- near 138B.

(4) Shape.--Oval, pointed.

(5) Texture.--Upper side is semi-glossy; underside is matte.

(6) Edge.--Serrated.

(7) Serration.--Shallow.
